I received 3 shots and conceived about 7 months after stopping depo, my period came back immediately, I wasn’t really trying but it did take ONE time to conceive, i BD once on my fertile week and fell pregnant. So I believe it really depends on the person. My sister received only 2 shots and her period didn’t come till 3 months after stopping depo and they’re still irregular. I didn’t do anything I just think it depends on the person.
